testing ubuntu 17.10 - session crash after monitor disconnection

I'm testing Ubuntu 17.10 installed on Lenovo PC (with Intel Core i5-6500 CPU and Intel HD Graphics 530 (skylake GT2) and after some update from the beginning of September Session is crashing (login screen is displayed again) every time I change the monitor Input (e.g. from DP to HDMI) or switching off the monitor (session is loosing video output). Same situation is for both session types, default Wayland and also for X.org.
Please, do you someone observe same behaviour?
